An occipital meningocele was detected by transvaginal sonography in a fetus of 13 weeks' gestation. This changed at 14 weeks to a cephalocele, which disappeared at 15-16 weeks and was detected again at 19 weeks. It is possible that sliding backward and forward of the herniated brain tissue caused this sequence of events.
在一名妊娠13周的胎儿中，经阴道超声检查发现枕部脑膜膨出。在14周时变为脑膨出，在15 - 16周时消失，并在19周时再次被检测到。有可能是疝出的脑组织前后滑动导致了这一系列事件。
